One test unit fails because of different Data::Dumper indentation. The strange thing is it should fail even on localhost with perl-5.10.1. Data::Dumper indents local and package (AST) structure in different way. I don't know how is it possible. However it does not fail.

How To Test

User Experience

User could notice warnings about soon to be removed modules e.g. Class::ISA will be removed, install from CPAN and errors in syntax e.g. defined(%hash) isn't supported anymore. These warnings are fixed in Fedora's modules, but it could be still found in users scripts.
